Sažetak
This paper refers to the influence of K fertilization on K, Ca and Mg relations in strawberry cv. Elsanta grown in peat mix, in a plastic greenhouse with vertical pot system. Four fertilization variants (control - 0.72 g K plant-1 as KNO3 and three variants with 2.22 g K plant-1 as the combinations of KNO3 and K2SO4, KCl or KHCO3) were applied using trickle irrigation in fruit bearing stage in autumn. The amount of K leached through the verticals containing eight pots and four plants per pot was influenced mostly by K rate. The highest yield was obtained on control variant with lower K dose applied as nitrate. The enhanced K rate influenced on leaf K concentration, showing significant differences among the applied combinations of K salts and the antagonism with Mg uptake was observed. The possible role of accompanying anions in the nutrient relations in soilless grown strawberries needs to be further elucidated.
